Definitions

  • the present invention relates to a novel protein formulation.
  • the invention relates to a liquid pharmaceutical composition of adalimumab, to a method of manufacturing the composition, to a kit including the composition, to a package including the composition, to a method of manufacturing the package, and to methods of treatment using the composition and/or package.
  • tumour necrosis factor-alpha (TNF-a)-related autoimmune diseases such as rheumatoid arthritis, psoriasis and other autoimmune diseases
  • FDA-approved drugs such as Adalimumab (HUMIRA®, Abbott Corporation).
  • Adalimumab is a human monoclonal antibody that inhibits human TNF-a activity so as to prevent it from activating TNF receptors, thereby downregulating inflammatory responses associated with autoimmune diseases.
  • Approved medical indications for Adalimumab include rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn's disease, ulcerative colitis, moderate to severe chronic psoriasis and juvenile idiopathic arthritis.
  • Adalimumab is generally delivered to a patient via subcutaneous injection, and is thus provided in a liquid form, typically in packages such as vials, preloaded syringes, or preloaded "pen devices".
  • Commercially available pen devices (HUMIRA ® Pen) generally include a 1 mL pre-filled glass syringe, preloaded with 0.8ml_ of a sterile formulation of 40 mg Adalimumab (see below), with a fixed needle (either gray natural rubber or a latex free version) and a needle cover.
  • Commercial formulations (HUMIRA ® ) of Adalimumab contain the following ingredients:
  • Citric Acid Monohydrate 1.04 1.3
  • Adalimumab, and its method of manufacture, is described in W097/29131 (BASF) as D2E7, and elsewhere in the art.
  • Adalimumab is stable (at least to some extent), the relevant antibody may be unstable over prolonged periods or under stressed conditions, thus precluding prolonged storage of said formulations. Such degradation of the formulation may be due to a variety of factors, including:
  • the primary goal of formulation development is to provide a pharmaceutical composition that will support the stability of a biopharmaceutical protein during all stages of its production, storage, shipping and use. Another goal for formulations that are meant for subcutaneous administration is to reduce injection pain.
  • Formulation development for an innovative biopharmaceutical protein, or a biosimilar monoclonal antibody (mAb) is essential to its safety, clinical efficacy and commercial success.
  • any new formulations would solve at least one of the aforementioned problems and/or at least one problem inherent in the prior art, and may suitably solve two or more of said problems.
  • the problem(s) of the prior art may be solved whilst reducing the complexity of the formulation.
  • EDTA stabilizes formulations comprising adalimumab.
  • the stabilizing effect is further increased if EDTA is added together with a small polyol, e.g., a polyol having 2 to 6 carbon atoms, such as glycerol.
  • the formulations of the invention are stable even at high concentrations of adalimumab (e.g., 100 mg/ml). Therefore, the new formulations permit administration of high amounts (e.g., effective amounts) of antibody in smaller volumes as compared to the aforementioned commercial adalimumab formulation, thereby decreasing pain.
  • high amounts e.g., effective amounts
  • a liquid pharmaceutical composition comprising:
  • EDTA suitably at a concentration of at most 0.14 mM EDTA
  • composition is suitably free or substantially free of one or more of:
  • a buffer system comprising phosphate and/or citrate

  • composition has a pH between 4.0 and 6.0.
  • liquid formulation according to item 8 comprising:
  • composition has a pH between 4.8 and 5.4.
  • liquid formulation according to item 9 comprising, consisting essentially of, or consisting of:

  • a solid composition obtainable by freeze-drying a liquid pharmaceutical composition as defined in any of items 1 to 16.
  • liquid pharmaceutical composition according to any one of items 12 to 16, wherein the composition is is free of, substantially free of, or comprises at most 40 mM of a tonicifier.

  • a biosimilar may have a (slightly) different glycosylation profile, even if the protein sequence is substantially the same or different to the extent specified above.
  • biosimilar also known as follow-on biologies
  • biologicales are well known in the art, and the skilled person would readily appreciate when a drug substance would be considered a biosimilar of adalimumab. Furthermore, such "biosimilars” would need to be officially approved as a “biosimilar” for marketing before said “biosimilar” is sold on the open market.
  • biosimilar is generally used to describe subsequent versions (generally from a different source) of "innovator biopharmaceutical products” ("biologies” whose drug substance is made by a living organisim or devived from a living organism or through recombinant DNA or controlled gene expression methodologies) that have been previously officially granted marketing authorisation.
  • biologies have a high degree of molecular complexity, and are generally sensitive to changes in manufacturing processes (e.g. if different cell lines are used in their production), and since subsequent follow-on manufacturers generally do not have access to the originator's molecular clone, cell bank, know-how regarding the fermentation and purification process, nor to the active drug substance itself (only the innovator's commercialized drug product), any "biosimilar" is unlikely to be exactly the same as the innovator drug product.
  • the molecular weight of adalimumab may be taken to be 144190.3 g/mol (reference molecular weight) based on details disclosed on the CAS database for CAS # 331731 -18-1 , Adalimumab, where the molecular formula is taken as C6428H9912N1694O1987S46.
  • a liquid pharmaceutical composition containing 50 mg/mL adalimumab may be considered a 0.347 mM (or 347 ⁇ ) solution of adalimumab.
  • references herein to EDTA includes salts of EDTA as well as non-salt forms of EDTA. Such references also encompass hydrates of EDTA or salts thereof.
  • EDTA may exist in a salt or partial salt form within the final liquid pharmaceutical compositions. The exact prevailing salt form(s) suitably depends on factors such as pH and other ingredients (including salts) present within the composition.
  • Particular salts of EDTA may include sodium salts, for instance: mono-sodium, di-sodium, tri-sodium, and/or tetra-sodium salts of EDTA.
  • Mixed salts, such as calcium disodium EDTA are also viable.
  • EDTA mono-hydrochloride or di-hydrochloride salts of EDTA may also be used.
  • the EDTA added to formulations of the invention as a sodium salt of EDTA, suitably an EDTA disodium salt or a hydrate thereof.

  • buffer or “buffer solution” refers to a generally aqueous solution comprising a mixture of an acid (usually a weak acid, e.g. acetic acid, citric acid, imidazolium form of histidine) and its conjugate base (e.g. an acetate or citrate salt, for example, sodium acetate, sodium citrate, or histidine) or alternatively a mixture of a base (usually a weak base, e.g. histidine) and its conjugate acid (e.g. protonated histidine salt).
  • the pH of a "buffer solution” will change very only slightly upon addition of a small quantity of strong acid or base due to the "buffering effect" imparted by the "buffering agent".
  • a “buffer system” comprises one or more buffering agent(s) and/or an acid/base conjugate(s) thereof, and more suitably comprises one or more buffering agent(s) and an acid/base conjugate(s) thereof, and most suitably comprises one buffering agent only and an acid/base conjugate thereof.

  • the overall pH of the composition comprising the relevant buffer system is generally a reflection of the equilibrium concentration of each of the relevant buffering species (i.e. the balance of buffering agent(s) to acid/base conjugate(s) thereof).
  • buffering agent refers to an acid or base component (usually a weak acid or weak base) of a buffer or buffer solution.
  • a buffering agent helps maintain the pH of a given solution at or near to a pre-determined value, and the buffering agents are generally chosen to complement the pre-determined value.
  • a buffering agent is suitably a single compound which gives rise to a desired buffering effect, especially when said buffering agent is mixed with (and suitably capable of proton exchange with) an appropriate amount (depending on the pre-determined pH desired) of its corresponding "acid/base conjugate", or if the required amount of its corresponding "acid/base conjugate” is formed in situ - this may be achieved by adding strong acid or base until the required pH is reached.
  • An acetate “buffering agent” is suitably an acetate salt, for example, sodium acetate, suitably mixed with its acid/base conjugate, acetic acid.
  • a buffer system may be formed by simply mixing a given amount of sodium acetate with a given amount of acetic acid (or indeed another acid, e.g. HCI).
  • a buffer may be formed by adding a given amount of a base, suitably a strong base (e.g. sodium hydroxide) to the acetic acid until the desired pH (and thus the desired balance of sodium acetate/acetic acid) is reached.
  • any concentrations given in relation to an acetate buffer or acetate buffering agent suitably refer to the combined concentration of the buffering agent(s) (e.g. sodium acetate) and/or acid/base conjugate(s) thereof (e.g. acetic acid).

  • buffering species refers to the particular species (excluding any associated counteranions or countercations - i.e. ignore sodium ions for sodium acetate/acetic acid systems) of a given buffer system which are in dynamic equilibrium with (and proton-exchange with) one another.
  • acetate anions and acetic acid together constitute the "acetate buffering species" of a "acetate buffer system”.
  • weight-based quantities may instead be determined by reference to a theoretical weight of the relevant "buffering species". At least two species are present in any given set of “buffering species” (in relative amounts that can only be determined by reference to the pH), each with a different molecular weight (which usually differs by just 1 ). Therefore, to enable viable weight calculations and references, for the purposes of this specification the weight of any given set of "buffering species” is given as a theoretical weight based on just one of the buffering species, namely the most acidic of the buffering species (i.e.
  • the weight of a given set of "buffering species” is quoted as the weight of acid-species equivalents.
  • the acetate buffering species may consist of acetate anions (ignore countercations) and acetic acid.
  • the weight of the "buffering species” is therefore calculated as if acetic acid was the only species present in the buffer system (even though acetate is clearly present alongside acetic acid).
  • any reference to a weight or weight ratio involving a "acetate buffering species” suitably refers to the theoretical weight of acetic acid equivalents within the buffer system.
  • a composition is formed by adding a pH adjuster (e.g.
  • the original weight of acetic acid may be considered to be the weight of the "buffering species" regardless of the ultimate pH.
  • concentration i.e. molarity

This may suitably include natural and/or artificial amino acids.
  • references are not intended to relate to amino acid residue(s) covalently incorporated as part of a larger compound (as opposed to a composition comprising multiple compounds), such as a peptide or protein (where such amino acid residues are linked via peptide bonds).
  • adalimumab as a protein, contains amino acid residues, it is not considered to comprise any "free amino acid(s)".
  • a composition defined as being "free of arginine” does not contain any free arginine but it may still include one or more proteins (e.g. adalimumab) which do themselves comprise arginine residues.
  • references herein to any one or more "amino acids”, whether specific or general, suitably relate to the L- stereoisomers or a racemate thereof, most suitably L-amino acids.
  • a "strong acid” is suitably one having a pK a of -1.0 or less, whereas a “weak acid” is suitably one having a pK a of 2.0 or more.

  • a “stabiliser” refers to a component which facilitates maintainance of the structural integrity of the biopharmaceutical drug, particularly during freezing and/or lyophilization and/or storage (especially when exposed to stress). This stabilising effect may arise for a variety of reasons, though typically such stabilisers may act as osmolytes which mitigate against protein denaturation.
  • Typical stabilisers include amino acids (i.e. free amino acids not part of a peptide or protein - e.g. glycine, arginine, histidine, aspartic acid, lysine) and sugar stabilisers, such as a sugar polyol (e.g. mannitol, sorbitol), though the liquid pharmaceutical compositions of the invention include EDTA and a C2-C6 polyol as stabilisers.
  • a "polyol” is a substance with multiple hydroxyl groups, and includes sugars (reducing and nonreducing sugars), sugar alcohols and sugar acids.
  • the polyol is a sugar alcohol.
  • any given "polyol” may be defined by reference to a number of carbon atoms contained within the molecular structure of the polyol.

  • Amounts of any corresponding non-anhydrous forms e.g. monohydrates, dihydrates, etc. may be readily calculated by simply using the appropriate multiplier.
  • amounts stipulated in relation to trehalose refer to the anhydrous form of trehalose (or compositions formed by using the stipulated amounts/concentrations of anhydrous trehalose), which has a molecular weight of 342.296 g/mol, so to calculate the corresponding amount of trehalose dihydrate needed to form the same composition (less water would have to be added) it is necessary to multiply the stipulated amount by 378.33/342.296, since 378.33 is the molecular weight of trehalose dihydrate.

  • a “therapeutically effective amount” or “effective amount” of the antibody means an amount that is effective, when administered to a mammal for treating a disease or disorder, in prophylactic and therapeutic aspect and the antibody is effective in treatment of the diseases concerned.
  • the "therapeutically effective amount” will vary depending on the compound, the disease and its severity and the age, weight, etc., of the mammal to be treated.
  • human TNF-a refers to the human cytokine which exists in a 17kD secreted form and a 26kD membrane-associated form, and in a biologically active form, TNF-a could be observed as a trimer of covalently-bound 17kD molecule. Its specific structure can be found in Pennica, D. et al. (1984) Nature 312: 724-729; Davis, J. M. et al. (1987) Biochemistry 26, 1322-1326; and Jones, E. Y. et al. (1989) Nature 338: 225-228.

  • the weight percentage balance may optionally be made up to 100 wt% by unspecified ingredients (e.g. a diluent, such as water, or other non-essential but suitable additives).
  • the term "parts" when used in relation to multiple ingredients/components, refers to relative ratios between said multiple ingredients/components. Expressing molar or weight ratios of two, three or more components gives rise to the same effect (e.g. a molar ratio of x, y, and z is xi : yi : zi respectively, or a range xi-x ⁇ : yi-y2 : Z1-Z2).
  • any or all such wt% values may be converted to parts by weight (or relative ratios) to define a multi-component composition. This is so because the relative ratios between components is often more important than the absolute concentrations thereof in the liquid pharmaceutical compositions of the invention.
  • a composition comprising multiple ingredients is described in terms of parts by weight alone (i.e. to indicate only relative ratios of ingredients), it is not necessary to stipulate the absolute amounts or concentrations of said ingredients (whether in toto or individually) because the advantages of the invention can stem from the relative ratios of the respective ingredients rather than their absolute quantities or concentrations.
  • such compositions consist essentially of or consist of the stipulated ingredients and a diluent (e.g. water).
  • composition is said to comprise a plurality of stipulated ingredients (optionally in stipulated amounts of concentrations), said composition may optionally include additional ingredients other than those stipulated.

  • composition where a composition is said to "consists essentially of" a particular component, said composition suitably comprises at least 70 wt% of said component, suitably at least 90 wt% thereof, suitably at least 95 wt% thereof, most suitably at least 99 wt% thereof.

  • SATP is a temperature of 298.15 K (25 °C, 77 °F) and an absolute pressure of 100 kPa (14.504 psi, 0.987 atm).
  • References herein to "standard pressure” suitably refer to an absolute pressure of about 100 kPa.
  • composition when used in relation to a given component of a composition, refers to a composition to which essentially none of said component has been added.
  • a composition is “substantially free” of a given component, said composition suitably comprises no more than 0.01 wt% of said component, suitably no more than 0.001 wt% of said component, suitably no more than 0.0001 wt%, suitably no more than 0.00001 wt%, suitably no more than 0.000001 wt% thereof, most suitably no more than 0.0001 parts per billion (by weight).

  • the present invention provides alternative and improved liquid pharmaceutical compositions, which are highly stable even at high adalimumab concentrations and therefore cause little pain upon injection.
  • the liquid pharmaceutical formulations of the present invention have comparable or improved characteristics when compared to the conventional formulations of adalimumab, for example the aforementioned commercially available formulation Humira®, when subjected to different stressing conditions (thermal, mechanical and light). Their performance is also generally comparable or better than many other comparative formulations that were subjected to the same stress testing.

Abstract

La présente invention concerne de nouvelles compositions pharmaceutiques liquides d'adalimumab, qui comprennent de l'adalimumab ou un biosimilaire de celui-ci, de l'EDTA et un petit stabilisateur polyol, tel que le glycérol. Une telle combinaison de constituants permet d'obtenir des formulations ayant une stabilité (par exemple, lors du stockage et lorsque la formulation est exposée à un stress) qui est comparable à ou une amélioration de la stabilité de formulations connues dans l'état de la technique, et ce, avec moins d'ingrédients. De tels avancées vont aider les traitements par adalimumab à devenir plus largement disponibles à moindre coût, et à prolonger la viabilité de dispositifs d'administration pré-chargés (par exemple, des seringues pré-remplies) pour réduire les pertes de médicament inutiles.
